MAGAZINE- GUN.

Specification of Letters Patent.

Patented Maia 1S, 1913.

Original application filed February 14, 1912, Serial No. 677,544. Divided and this application filed October T all whom it may concern Be it known that I, NORMAN B. RANDALL, a cltizen of the United States, reslding at Boston, in the county of Suffolk and State vention resides in providing an improved indicating means whereby the number of shells remaining in the magazine after a portion thereof have been fired may be readily noted by the gunner.

A further object of the invention resides in providing means which, while acting in the capacity of an indicating means, will also reserve the last shell of the' magazine and a still further object resides in the provision of a means which is extremely simple and durable in construction, inexpensive to manufacture and one which will be very etlicient and useful 1n operation.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application, Figure 1 is a fragmentary side elevation of a gun showing my improved device applied to use thereon. Fig. 2 is a fragmentary vertical longitudinal section therethrough. Fig. 3 is a vertical trapsverse section as seen on line 33, Fig. {1i Fig. 4 is a horizontal section as seen on lined-4, Fig. 3. Fig. 5 is a perspective view of one of the levers used in the indicating mechanism of the device; and Fig. 6 is a similar view of another one of the lovers used in the indicating mechanism.

In describing my invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which 1 indicates a stock, such as-is used in shoulder. guns of the present day, to which is secured a metallic receiving casing or f ame sa d fr me or receiver having an Serial No. 725,483.

npper tubular portion which has threaded into engagement therewith a barrel casing 3. This barrel casing is braced in the usual manner by the forearm 4 and slidably disposed in the barrel casing 3, is a barrel 5, the inner end of which has a breech block 6 slidably mounted therein. The frame 2 has pivotally mounted therein the usual hammer 7 and trigger 8, the latter operating the former through the medium of a scar 9 carried on the end of a lever 10 also pivoted in the frame 2. As the above referred to portions of the gun, together with their adjunctive parts form no part of my invention, further description of the operation and construction thereof will be omitted.

The barrel 5 has a chamber 11 formed adjacent the inner end of the same which is adapted to communicate, in a particular position of said barrel, with a chamber 12 formed in the frame 3. This chamber is positioned in the frame just forward of the trigger 8 and is adapted to receive therein a magazine 13 ofthe usual type containing a plurality of shells 14:. This magazine being of the usual type contains a spring follower 15 to force the shells upwardly intoposition to enter the socket 11 of the barrel at a predetermined time and in order to lock said magazine in position, a pawl 16 is provided which is pivotally carried on the frame 2 and adapted to be operated by the gunner. This pawl is adapted to extend through an opening in the magazine to retain it in position as shown in Fig. 2 of the drawings and a spring forced pin 17 carried in the 1 solid portion of the frame 2, immediately forward of the trigger uard normally retains said pawl in its efiective position.

The primary object of my invention is to provide an indicating mechanism for the number of shells remaining in the magazine after a portion thereof have been fired and to this end, I provide a plurality of lovers 18, I having shown but two in the drawings,

said levers being L-shaped and pivoted at the intersections of, the arms thereof, within the frame immediately in the rear of the magazine. These levers are so arranged as to normally dispose one arm of the same horizontally and the other arm thereof vertically, the vertical arms of said levers being provided With lugs 19 at the free ends of the same which are adapted to project through the respective slots 20 in the mega 11 many levers may be provided as are desired,

and an additional pair of levers 22 are also provided, the same being pivotally mounted in a casing 23 on an axis at right angles to the pivotal axis of said levers 18. This casing 23 forms a projecting housing on the one face of the covering 24 which is provided for the parts of the gun, said covering having an openin therein to allow the housing to communicate with the portion of the frame 2 inclosed within said covering. These levers 22. are also of the substantially L-shaped type and have the horizontal portions thereof in position to rest respectively on the horizontal portions of the levers 18, whereby when said latter levers are swung on their pivots, the lovers 22 will also be swung. In order to normally retain the horizontal portions of the levers 2-2 in-contact with the levers 18, the spring forced pins 26 are mounted in the bottom of the housing or casing 23 and engage projections 27 formed on said levers 22 and thus it will require a movement of the levers 18 in order to swing said levers 22 on their pivots.

The free ends of the substantially vertically extending arms of the levers 22 are provided with dials 27 upon which may be printed any indication desired whlch will represent the number of shells remaining in the magazine and the rear wall of the housing 23 is formed of glass or other transparent material as shown at 28, whereby the operator of the device may readily observe the dials as the same are brought into position.

As the shells with which the lugs on the vertical portions of the levers 18 contact, are discharged from the magazine, said levers will be swung on their pivots so that the free ends of the horizontal arms thereof will be swun upwardly and thus said levers 22 19 theredf will be disposed in the .one slot of the magazine casing. The swinging of this lever on its pivot will, obviously, force the one indicating lever 22 to be swung on its pivot to correspondingly disclose the indicating disk, the latter showing the numeral 2 to disclose the number of shells remaining in the casing. lVhen there is but one shell left,- the other-of the pair of levers 18 will be swung on its pivot to swing the corresponding indicating lever therewith and disclose the indicating disk having the numeral 1 thereon. When this last mentioned lever 18 is swung on itspivot, the free or raised end of the same interferes with the operation of --the sear 9,30 that the same cannot be moved by the trigger to release the hammer. Thus, this mechanism acts as a reserve for thelast shell in the magazine,-but I have also provided a means for disposing this one lever out of its inter fering position with the sear and to this end, a pin 28 is extended transversely.of the frame 2 immediately above the horizontal portions of said levers 18. This pin or shaft 28 has a flat portion 29thereon which, when disposed downwardly facing the horizontal portions of the levers 18 .will permit said levers to be swung on their pivots the full distance and thereby accomplish the desired result of reserving the last shell. WVhen this pin 28 is turned by means of the hand lever 80, however, the round or full portion of the pin will contact with said horizontal portions of the levers 18 to force the same downwardly and out of the path of the sear 9. The sear may then be operated to allow the hammer to be released. This hand lever 30 is mounted on the one end of the pin 28 and is disclosed in Fig. 1 of the drawings, the same being in a position to be readily operated, at w1ll,-by the unner. From the foregolng description of the construction of my improved indicating mechanism, for magazine guns, the operation thereof will be readily understood and it will be seen that I have provided a simple, inexpensive and eflicient means for carrying out the objects of the invention.

While I have particularly described ,the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in theminor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.
